Merge Min_circle_2, Min_ellipse_2, Min_sphere_d, Min_annulus_d,
Min_sphere_of_spheres_d, Min_quadrilateral_2 and
Approximate_min_ellipsoid_d. The documentation from the part that is
in Matrix_search has also been moved here, but not the code. Add a new
don't submit that covers the old ones, combine the package_info
files. Examples and tests are still in separate folders. Merge them in
a separate step.
